A grimy snapdragon is a herb that has not yet been cleaned to make a snapdragon. Grimy snapdragons may be grown from a snapdragon seed with a Farming level of 62, giving 98.5 experience for every snapdragon grown. Once planted, the herb takes 80 minutes to fully grow. It is possible to grow 3-18 snapdragons from one seed or 5-24 if using supercompost and magic secateurs.

Cleaning a grimy snapdragon requires a Herblore level of 59 and gives 11.8 Herblore experience. Clean snapdragons are used to make super restore potions and sanfew serums with a Herblore level of 63 and 65 respectively.

They are received as a drop from some high levelled monsters like General Graardor. 1-3 grimy snapdragons are a possible reward from the Gnome Restaurant minigame.
